HEX 2026 is a new two-night bass music festival built around Halloween weekend. It runs Friday, October 30 and Saturday, October 31, 2026 on the Festival Grounds at Rawhide Western Town & Event Center, 5700 W North Loop Rd, Chandler, AZ 85226, in the Phoenix metro area. It is presented by Relentless Beats, the Arizona promoter behind Decadence Arizona and Goldrush, under its bass sub-brand Aftershock. The Relentless Beats event page lists doors and music at 5:00 PM and a 1:00 AM curfew on both nights, and the event is 18+ with a government-issued ID required. The official site bills it as a "Bass Music Halloween Experience", and the 2026 edition is the first one.

The full 2026 lineup is out: 22 artists, split by day on the official lineup page. Friday is led by Subtronics and INZO, with Badklaat, Dennett, Inaktiv, Izzy Vadim, Layz, Nikademis, Onara, Sora and local guest Linz. Saturday, Halloween night, is led by Excision and ATLiens, with Decimate, Hurtbox, Modal Nodes, Proxxxy, Riot Ten B2B PhaseOne, Softest Hard, Xaebor, YVM3 and local guest DeathBeat. The official lineup page tags the four headliners to a stage called The Altar. The June announcement, as reported by Dubstep FBI and Fresh Music Freaks, describes two stages: a main stage for the biggest productions and a second stage focused on bass and riddim. Set times had not been posted on the official site as of October 3, 2026.
Rawhide is a 160-acre venue on the Gila River Indian Community directly off I-10 in Chandler, with a replica 1880s Western town next to the open-air Festival Grounds lawn where HEX takes place. The Relentless Beats venue page puts overall capacity at 10,000 and the on-site parking lot at roughly 4,000 spaces. The venue has been cashless for food and drink since October 1, 2024 and enforces a clear bag policy. What sets HEX apart from the rest of the Relentless Beats calendar is the date: it lands on Halloween itself, costumes are part of the point, and the bill is bass-only, with no house or trance stage. Relentless Beats runs Obsidian in Phoenix the following weekend and Decadence Arizona at Phoenix Raceway on December 30 and 31, so HEX is the opening act of its fall and winter festival run.
